The Gonksi reforms, renamed Better Schools, is a plan to roll out additional funding to schools over six years, with the amount of money increasing each year of the plan.

Terry Polglase, Tasmanian president of the Australian Education Union, says the plan would see all public schools better off, particularly in the longer term.

"We estimate that probably no more than five to 10 schools will be less off than what they are this year, but most schools will be considerable better off.

"No school will be getting any less than a five per cent increase in their resource package and probably 60 per cent of them will be receiving somewhere between 20 and 30 per cent."

Under the plan Tasmanian schools will receive an additional $8 million next year, with the increased funding reaching $74 million in the sixth year of the Better Schools plan.

But Mr Pyne says the deal with never finalised and the new federal government, meaning they are not obligated to honour it.

"I truly believe that his [Mr Pyne] intention is to not provide that funding," says Mr Polglase.

"Every child deserves and equal chance at education and Gonksi's the only program that can actually deliver that.

"Christopher Pyne has come up with nothing as an alternative."

Nick McKim, Tasmanian Education Minister, says the Tasmanian Government has signed a memorandum of understanding and a heads of agreement with the previous federal government.

"We signed a memorandum of understanding and a heads of agreement with the Commonwealth Government that was signed by the premier Lara Giddings on behalf of the Tasmanian government and we would expect that to be honoured by Christopher Pyne and Tony Abbott.

"Anything other than that would be ripping money out of our education system and ripping money therefore out of Tasmania and Australia's future."

Mr McKim says he does welcome Mr Pyne's review of the act regarding how the money can be spent, as he says the act was too prescriptive before.

"That act was very prescriptive...we thought it was too prescriptive and Christopher Pyne has said he would wind back some of the central command and control aspects of that act which we think is a good thing for Tasmanian schools."

Mr McKim says he will be pushing for the Better Schools plan to be honoured in full by the federal government.

"I'm going to be very clear that we expect them to honour their commitments around Gonksi and Better Schools."
